spring-boot - Spring Boot Oauth2 资源服务器 UserDetailsS​​ervice

Question

试图让 UserDetailsS​​ervice 为我设置的 oauth2 资源服务器工作。我能够成功地对 jwt 进行身份验证，但我所做的一切似乎都无法让它调用 loadUserByUsername 方法。这最初是使用 SAML 并且它正在工作，但现在我已经切换到 Oauth2 并且我无法让它工作。

     @Service
     public class OauthUsersDetailsServiceImpl implements UserDetailsService{
         @Override
         public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
             //some user loading junk here - this is never called
         }
     }

     @Configuration
        @EnableGlobalMethodSecurity(prePostEnabled = true)
        @EnableWebSecurity
         public class SecurityConfig extends WebSecurityConfigurerAdapter {
            
            @Override
            protected void configure(HttpSecurity http) throws Exception
            {
                //test key for now
                SecretKeySpec key = new SecretKeySpec("private key0000000000000000000000000000000".getBytes(), "HMACSHA256");
                

                http
                    .authorizeRequests()
                    .antMatchers(/*some endpoints im excluding from auth - this all works*/)
                    .permitAll().and()
                    .authorizeRequests()
                    .anyRequest().authenticated().and()
                    .oauth2ResourceServer().jwt().decoder(NimbusJwtDecoder.withSecretKey(key).build());
            }
         }

我在谷歌上发现我可以用@service 将这个类注册为一个 bean，而 spring 只会把它捡起来，但它不起作用。我也尝试通过 AuthenticationManagerBuilder 添加它，但这也不起作用。我的猜测是 jwt 方面有它自己的 UserDetailsS​​ervice，它实现了并且优先于我的。也就是说，让我的调用的正确方法是什么，或者在身份验证完成后以某种方式手动调用我的用户加载逻辑并覆盖 Principal 对象更好？我需要在调用端点之前执行此操作，以便 PreAuthorize 可以检查由 UserDetailsS​​ervice 加载的角色。

弄清楚了。希望这会帮助遇到相同问题的任何人。我必须在链中添加一个自定义过滤器来调用我的用户详细信息服务并覆盖上下文:

public class Oauth2AuthorizationFilter extends GenericFilterBean {

        @Autowired
        private OauthUsersDetailsServiceImpl oauthUsersDetailsServiceImpl;
      
      public Oauth2AuthorizationFilter (OauthUsersDetailsServiceImpl userDetailsService) {
        this.oauthUsersDetailsServiceImpl = userDetailsService;
      }
      
      
      @Override
      public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
          throws IOException, ServletException {

        SecurityContext context = SecurityContextHolder.getContext();
        if(context.getAuthentication() != null && !(context.getAuthentication().getPrincipal() instanceof Users)) {
          
          UserDetails user = oauthUsersDetailsServiceImpl.loadUserByUsername(((Jwt)context.getAuthentication().getPrincipal()).getClaimAsString("user_name")); 
          UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(user, null, user.getAuthorities());
          context.setAuthentication(authentication);
        }
        
        chain.doFilter(request, response);
      }

    }

@Override
        protected void configure(HttpSecurity http) throws Exception
        {
            //test key for now
            SecretKeySpec key = new SecretKeySpec("private key0000000000000000000000000000000".getBytes(), "HMACSHA256");
            
            http.authorizeRequests().antMatchers(/*bunch of junk...*/).permitAll().and().authorizeRequests().anyRequest().authenticated().and()
                .oauth2ResourceServer().jwt().decoder(NimbusJwtDecoder.withSecretKey(key).build());
            
            http.addFilterAfter(jwtAuthTokenFilterBean(), SwitchUserFilter.class);

        }

这终于做了我需要的
